I want to create a mobile learning for an high school. Is there a way to display math notation like square, exponent etc in textview? Or should we use another component?

I've been looking around for an app or game that helps you learn to read musical notation and increase score reading speed/accuracy (piano - treble and bass cleffs). Anyone know of an app like this for android?
I shot an email to LogicFoundry (dev for Winmo) and asked them-- waiting to hear back.

I want to display it in TextView. How to do this?
I have a view in which there is a text box where user enters data, when clicks on submit, I want to store the input and display in another box. final EditText edittext = (EditText) findViewById(R.id.edittext); mText = (TextView) findViewById(R.id.timepicker_input);

View 1 Replies View RelatedI am working on an Android application that displays a list of items when a tab is selected, then displays detail information about an item that was selected from the list :
CODE:............
The details are to be displayed using ImageViews, ImageButtons, and TextViews. The data comes from a database query, so the TextView text and ImageView drawables have to be assigned dynamically.
The correct text from the database query gets assigned to each of the Views. I can see everything being added when I step through the code in the onCreate method of Activity3 in the debugger.
BUT, the drawables are only displayed when I select the first item in the ListActivity. If I select another item, all TextViews display the correct information but the drawables are not displayed for the ImageViews or ImageButtons. It looks like only the backgrounds are being displayed.
The ImageButton drawables are not being dynamically assigned, only the ImageView drawables are. The ImageButton drawables are set in the TableLayout XML that is associated with the activity. Here is one entry :
CODE:..............
Originally, I had android_drawable="@drawable/ic_phone", then tried adding android:background="@drawable/ic_phone", and finally created the following selector (phoneselector.xml) :
If I select the first item again, its proper ImageView drawables are displayed along with the proper text in the TextViews. The ImageView drawables that belong to the other items have no problems being displayed in Activity2's ListView.
The code successfully sets an onClickListener for the button (also in Activity3.onCreate). If I click on what is displayed on the spot where the drawable should be, the phone number is dialed.
The code successfully sets an onClickListener for the button (also in DetailActivity.onCreate).
Has anyone seen anything like this before? I would appreciate any help figuring out what is wrong.
Here are more details because I wonder if the problem has to do with the use of the Views :
The Activity1 extends TabActivity and sets a TabHost view that contains a FrameLayout along with the TabWidget. Activity1 creates the tabs dynamically.
Activity2 extends ListActivity and sets the content to its ListView (via setContentView(getListView()).
When ListActivity.onListItemClick is invoked (item in list is selected), a new Intent is created that contains an identifier in a Bundle and Activity3 is started.
The started activity (in Activity3.onCreate...) sets the content to a TableLayout view defined in a .xml file (via setContentView(R.layout.details.xml).
Here is the code from Activity3.onCreate :

i have a spinner with an arrayadapter that is dynamically managed. when it gets displayed, the spinner text also displays the radio button. how do i get rid of this radio button?
NOTE: i'm not talking about the radio buttons that appear in the list that is displayed when i select the drop down on the spinner.
here is a pic of what it looks like: SIGH cannot upload image as i don't have 10 pts. so i've found a link: http://www.slashresources.com/android-gui-examples/ scroll down about 1/2 way and find the spinner example on that page. and my spinner looks like the spinner thats grayed out by the list. notice how the drop down arrow is all strecthed and yucky... thats my problem.
Here are the appropriate code snippet... couple of points:
This code is in the constructor of widget which is a subclass of Spinner value is an array of Object instances (passed when the widget gets created) there are no XML resources; all widgets are dynamically created thinking i need to "manipulate" the prompt, i added setPrompt(...) in the constructor and also in the onitemclicked event listener... this had no effect.
Q: what am i missing? seems to me i'm missing some attribute of the Spinner which is causing the radio button to also display in the text part of the spinner.

View 1 Replies View RelatedIm the developer of a fairly new app the Math Alarm Clock. A month ago I looked for alarm clock which was a challenge to turn off and didnt find any on the market so I developed this. Basically you tell it how hard you want the math (4 levels of difficulty) from (5*8) to [(17*19)- 16*12)]. It is smart enough to never give you stupid easy questions such as (73-73) or (1*10). Then choose how many in a row you must answer correctly from 1 to 6 to turn off the alarm. Specify a few math-free snoozes if you like to snooze a few times before entering math. Or turn the math off completely and use it as a regular alarm.
The other unique feature is the music alarm. Of the other alarm clocks I found one required you to change music into a ringtone and the other only allowed you to pick one song. This alarm clock allows you to choose an individual song or choose a random song from a specific artist or a random song from a specific album.
And for any Canadian Rogers Dream or Magic users you may have noticed other alarm clocks will completely crash your phone and require a factory reset. This has been fixed in the Math Alarm Clock and it should work with no problem on HTC based phones.
Lastly as the comments point out, I respond to feedback very fast and for the most part have requested features implemented within 24 hours.
The last few comments:
"This developer rocks! I requested a feature and it was added within hours. This is the best alarm clock for the G1 hands down!" 5/5
"Great app, developer is quick to update. Highly recommend!" 5/5
"Awesome app!" 5/5
"Amazing! The only alarm that actually wakes me up" 5/5
I need maths for my game physics and lots of them, so I use the. Math library. And guess what? I never casted so much to floats in my entire life. And i know how costly it is to use doubles on an embedded device because I read the performance optimization page in the google android sdk docs. So I am wondering if we couldn't get a Math package with functions taking and returning floats instead of the default doubles. e.g. Math.sinf Math.cosf.

I just benchmarked (float)Math.atan2(x,y) and it's a very slow function. I checked FloatMath for Android 1.0 SDK and it has sin and cos but no tan or atan. Is there a faster way to do this?
View 2 Replies View RelatedI know this is more of a general programming question, but my Android friends here have always been helpful. I am trying to make an image move from one part of the screen to a position the user touches, as a constant speed. I don't know the best way to go about doing this and the way I have been trying to get to work is taxing my brain too much.
I have been using geometry to calculate slope, then using Sin * movement speed to calculate the difference in X,Y coordinates.
This is the codecode...
The problem that I'm having is the image is veering way of course when traveling in Y heavy paths. When traveling horizontally it works almost perfect.
I know there is probably an easier way though I don't know how to use a lot of things (like OpenGLES) so if your advice is to use a different method please link a tutorial for that method if you know of one.

View 2 Replies View RelatedI would like to have a layout with 5 times 5 buttons. Each of them should have the same width and height (they should be square). And I want the whole matrix to use the screen width (or height, depending on rotation).
I currently do it "by hand" in the Java code:

This can be improved by obtaining screen width first and then dividing by 5 to get rid of this literal 60. But I'm wondering how I can do this in the res/layout XML file? How can I specify for the height to be the same as the width? (I can set the width to match_parent.)

View 5 Replies View RelatedIn the spirit of using existing, tested and stable libraries of code, I started using the Apache-Commons-Math library and its BigFraction class to perform some rational calculations for an Android app I'm writing called RationalCalc.
It works great for every task that I have thrown at it, except for one nagging problem. When dividing certain BigFraction values, I am getting incorrect results.
If I create a BigFraction with the inverse of the divisor and multiply instead, I get the same incorrect answer but perhaps that is what the library is doing internally anyway.
Does anyone know what I am doing wrong?
The division works correctly with a BigFraction of 2.5 but not 2.51, 2.49, etc...
[UPDATE]
This was indeed a bug in the apache-commons-math 2.0 libraries. The bug is fixed in v.2.1.
It is now listed in the Fixed Issues section of the bug tracker:
When multiplying two BigFraction objects with numerators larger than will fit in an java-primitive int the result of BigFraction.ZERO is incorrectly returned..attempting to reproduce the issue and setting me on the right track.
